Check the Xorg log file, then you'll now, which driver had been chosen. By
the way, as far as I know, now there is only one intel driver, there is no
distinction between i810, i915 or i965 (I cannot see it in my distro).


The Xorg driver was renamed from "i810" to "intel" a couple years ago.
It is possible that an older version was still installed under the i810 name
on his system, or more likely that it wasn't really the driver change that made
a difference.

Thank you to all who responded.  You have made my understanding much 
more clearer.


Regards,

Phil

So if your machine is using a vesa driver, then its obvious that it makes no 
difference, whether you have i810 or i915 chipset. But this is vesa driver 
and its performance is lower than for intel driver.

By saying that there is no distinction between different intel models I 
meen, that now there is only one intel driver. I expect that it should check 
the chipset that you have and work well depending on it.

Hi Łukasz,

Thank you for replying, I did what you asked and found out that it used 
the vesa driver.  However, there must be a distinction between the i810, 
i915 or i965 drivers.  How else can the i810 work but the intel not?


Thanks again,

Phil

Xorg config question (missing xorg.conf)

2010-11-02 Thread Phil Savoie

Hi All,

Pardon me if this has been asked and answered but this is my situation. 
 On install of my optiplex gx210L with an intel915 chipset for the 
video driver, RH 5.4 install chose the intel driver which gave me a 
black screen and unresponsive computer.  After rebooting in single user 
mode I was able to vi the xorg.conf file and change the device to i810 
which works.


Now I have inadvertently deleted my xorg.conf file and rebooted yet 
video still works fine as if the xorg.conf file was still in place.


I understand that xorg will probe the device in the absence of an 
xorg.conf file and use the most appropriate driver.  But... what did it 
choose?  Why did it not choose the intel driver as on initial install? I 
would have expected another black screen, like on initial install.


Thanks in advance,

Phil
